Using the files in your post-production software

First, go to the ‘Files‘ app on your iOS device and find the file(s) that apply to your software of choice (see below). Transfer these to a folder on your computer, along with your footage.

ApplicationFiles needed
HitFilm.hfcs
Blender.hfcs and blender_hitfilm_importer.py
(The .py file is only needed once to install the add-on that handles files from CamTrackAR)
After Effects.jsx
(requires the paid version of CamTrackAR)
Plain Text.json and .csv
(requires the paid version of CamTrackAR allowing you to process the data in your own custom made programs/utilities)

In HitFilm

Go to the ‘Media’ panel > ‘Import‘ and import the .hfcs file. This will create a new composite shot. Then import your footage for a fully tracked scene.

In Blender

The first time you use CamTrackAR with Blender, you’ll need to go to ‘Edit’ > ‘Preferences’ > ‘Install’ and find the blender_hitfilm_importer.py file. This allows Blender to read the .hfcs files from CamTrackAR and only needs to be done once.

Then, all you need to do is import the .hfcs file under ‘File’ > ‘Import’ > ‘HitFilm AR Tracking Data’, and this will import the composite shot into Blender.

In After Effects (requires the paid version of CamTrackAR)

Go to ‘File’ > ‘Scripts’ > ‘Run Script File’ and open the .jsx file to create a composite shot in After Effects. Then import your footage for a fully tracked scene.
